Abstract

A security document is provided containing a color-forming composition having an insulating material therein which allows the document to be passed through heated printing devices such as laser printers without the problem of premature color development. The color-forming composition includes a mixture of a color former, a color developer, and an insulating material. In a preferred embodiment, a toner adhesion-enhancing composition containing an insulating material is applied over the color-forming composition. The security document may be used to provide an authentication feature and/or an indication of attempted alterations from the use of solvents, heat or abrasion.
